add support for kcm (klikogroep / klikocontainermanager)

[sndrsmnk]

Fixes #337

Other cities using KCM/klikogroep will need code changes.

I haven't (couldn't really) test if this breaks any other collectors. Please apply critical review. But it works for me. 👍

[sndrsmnk]

KCM/KlikoGroep calls for a "card number", but i decided to name that field "username", as it could actually be viewed as such. This allows other collectors with the same user/pass requirement to be implemented more cleanly.

Also, i dont fully understand the result set (getMyWasteCalendar). It returns an array of arrays, which has two items per array, one of which is always 0 (in my case). It could be that different cities collect two types of trash on the same day, perhaps? I dont know how afvalwijzer deals with multiple collection items on one day. This change could introduce that situation

@sndrsmnk thanks for your contribution! I'll do some testing later Today, but my assumption is that it will not break anything.
We'll see if "getMyWasteCalendar" is needed later. People start creating issues anyway when it is really an issue, so don't worry. I`m very happy that you contributed to this project! Many thanks.

Pre-release created: 2024.12.07-pre.1

[xirixiz]

Made some improvements/modifications in regards to error handling. But the pre-release seems to be working just fine.
If you can confirm everything is working from your end, I`ll draft a new release.

Currently running your improved version. Works just fine! I based the entire thing on the ximmio.py collector. ;))
